1980's honda hrs 21 mower help

[miatamama]

Hi! I am looking for help in repairing an old mower that was given to me. It wouldnt run so I started trouble shooting. What I have found is a bent intake pushrod and stuck valve. The problem is that I didnt mark the cam and flywheel. Does anyone know how to time the cam. I can not find any marks on the cam or crank. Any help would be appreciated. This mower looks like new and would be good for my trimming needs.

Robert, Thanks very much for sharing. I thought I would have to buy a manual and mower was free so would not have been worth the cost. Thanks again. John S
